FLOOD-ZONE MAP FEMA NFHL · LIVE Where the high-risk flood zones are in Mount Pleasant
This is Mount Pleasant drawn live from FEMA’s National Flood Hazard Layer. Every shaded area is a
Special Flood Hazard Area, a high-risk zone where a federally backed mortgage requires flood
insurance, and the first thing a carrier checks after a water loss. Your homeowners policy does not cover
flood; that takes a separate NFIP or private flood policy. Pan and zoom to your street to see your zone.
FEMA FLOOD ZONES · MOUNT PLEASANT Loading live data…
Zone VE
Coastal high-hazard. Storm surge with waves on top, the most dangerous zone, along the open water.
Zone AE
The 1%-annual-chance floodplain (the “100-year” zone). FEMA sets a Base Flood Elevation here.
A / AH / AO
Other high-risk areas, shallow sheet flooding, ponding, or floodplain not yet studied in detail.
Unshaded (X)
Moderate-to-low risk, not no risk. Over a quarter of federal flood claims come from outside the high-risk zones.
Drawn live from FEMA’s National Flood Hazard Layer. Absence of shading is not a guarantee against flooding; confirm your exact address at the
FEMA Map Service Center.
LIVE CONDITIONS NWS · NOAA · LIVE Radar, forecast & tides for Mount Pleasant
Live from the National Weather Service and NOAA, the local Doppler loop, the official 7-day forecast, and the
next high and low tides. Tides and surge timing decide how bad a coastal flood gets; a storm arriving at high
tide floods far more than the same storm at low tide.

How the risk changes across Mount Pleasant
Flood exposure is hyper-local. These are the broad patterns by area, keyed to FEMA zones and the way water
moves here, surge off the bay, the Charleston County river system, and low interior drainage. General
reference only; confirm your exact address on the map above.
